Actually just came across this tip:
Have you ever been annoyed by not being able to apply a blend mode to a collapsed layer? Don’t know what I’m talking about? Then try this: Precompose a layer (LAYER > PRECOMPOSE); in the switches column (F4) activate the Collapse Transformations switch (it looks like a little sun) for the new precomp; in the modes column (F4) you’ll notice that the blend mode popup menu has a little dash on it ““ letting you know blend modes are unavailable for the layer. Here’s the trick: Apply an effect to the collapsed precomp (this can be something like EFFECTS > EXPRESSION CONTROLS > ANGLE CONTROL that does nothing) and the blend mode popup will become active again. Thanks to Adobe’s Dave S. for this cool tip.
